--- _id: '1001' abstract: - lang: eng text: We present a computational approach for designing CurveUps, curvy shells that form from an initially flat state. They consist of small rigid tiles that are tightly held together by two pre-stretched elastic sheets attached to them. Our method allows the realization of smooth, doubly curved surfaces that can be fabricated as a flat piece. Once released, the restoring forces of the pre-stretched sheets support the object to take shape in 3D. CurveUps are structurally stable in their target configuration. The design process starts with a target surface. Our method generates a tile layout in 2D and optimizes the distribution, shape, and attachment areas of the tiles to obtain a configuration that is fabricable and in which the curved up state closely matches the target. Our approach is based on an efficient approximate model and a local optimization strategy for an otherwise intractable nonlinear optimization problem. We demonstrate the effectiveness of our approach for a wide range of shapes, all realized as physical prototypes. alternative_title: - ACM Transactions on Graphics article_number: '64' article_processing_charge: No author: - first_name: Ruslan full_name: Guseinov, Ruslan id: 3AB45EE2-F248-11E8-B48F-1D18A9856A87 last_name: Guseinov orcid: 0000-0001-9819-5077 - first_name: Eder full_name: Miguel, Eder last_name: Miguel - first_name: Bernd full_name: Bickel, Bernd id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 citation: ama: 'Guseinov R, Miguel E, Bickel B.
